I am attempting to install AADSyncServices (v.1.0.475.1202).
Going through the setup, I get to the last page and click on 'Configure'. I get "Unable to establish a connection to the authentication service. Contact Technical Support".
I did have the old version of sync services running, but no luck with the new version.
Two Events in Application Log
0- Unable to establish a connection to the authentication service. Contact Technical Support. GetAuthState() failed with -2147186688 state. HResult:0. Contact Technical Support. (0x80048862).
906- System.Management.Automation.CmdletInvocationException: Unable to establish a connection to the authentication service. Contact Technical Support. ---> Microsoft.IdentityManagement.PowerShell.ObjectModel.SynchronizationConfigurationValidationException: Unable to establish a connection to the authentication service. Contact Technical Support.
I can connect via Powershell and the web page without issue with the same account.
I am running on 2012 R2
